​Three years ago, scientists used Wi-Fi-equipped ground-based robots to obtain 2D images of objects hidden behind brick walls. Now, using aerial drones, they've obtained 3D images of similarly-hidden objects.

In the latest edition of "crowdfunding campaign: cool or crap?" comes Sound Heroes, a Bluetooth speaker in the shape of a humanoid robot. Apparently there are plenty who would place this one in the "cool" camp as the campaign reached its goal in only four minutes.

Concrete might seem like an odd material to make speakers out of, but it's not unheard of. Now, for its first foray into the world of wireless speakers, Master and Dynamic is launching the MA770, an industrial-chic concrete block with supposedly superior acoustics and a range of input options.

A few years ago, Sony released a business-focused e-paper tablet, and now the company has updated the device with higher resolution, bigger memory, NFC and Bluetooth connectivity, a new pen-friendly screen and a few bonus workflow features.

Wi-Fi works by sending information via radio waves, but systems that rely on light have the potential to achieve much faster speeds. A new system uses infrared rays beamed from antennas to reach data transfer rates of over 40 Gbps, regardless of how many devices are hooking into the network.

Airline passengers browsing the web using in-flight Wi-Fi might be forgiven for thinking they've stepped back in time to the age of dial-up. But now a team at Northwestern University has developed an extension for the Chrome browser that significantly speeds up page loading in the air.

When using public Wi-Fi, we don’t often think about the sensitive data that our phones, tablets and laptops are constantly transmitting. What exactly are the risks of using public Wi-Fi? How can you keep your data and devices secure?
